Solving the case: The opening scene solved a major shooting case, and the boss Ji Jie

Song An took a taxi back to the technical department of the police force. The chief, Wang Xiaoguang, was staring at a pile of ropes in a daze.

Wang Xiaoguang was about 30 years old, white and plump, with a cute voice. He had no temper with anyone and was a veritable"national treasure" of the Yanshan Police Department."

"Wang Ke, are you reading the rope's fortune?"

Song An patted Wang Xiaoguang's shoulder and said with a smile.

"You're just in time! Song An, how many minutes did it take you to untie the knot when you rescued someone last night?"

Wang Xiaoguang blinked his round eyes and looked at Song An.

Song An thought about it. After the victim woke up last night, Tian Rui used a flashlight and it was he who untied the knot for him.

"About ten minutes or so, what happened?" Song An asked curiously.

"Yeah! Xiaoguang, you lost, give me the money!"

Feng Jing poked her head out from behind the microscope, ran over happily, and stretched out her hand to Wang Xiaoguang.

Wang Xiaoguang sighed, took out ten yuan and threw it to Feng Jing.

Fang Yiren closed the DFO display box, walked to Feng Jing with a sullen look, and also took out ten yuan and handed it to her.

"What's going on? Are you from the technical department setting me up for a bet?" Song An said with a smile.

Feng Jing raised the banknotes in her hand proudly,"Our Section Chief Wang just took half an hour to untie the knot. I bet with them that Officer Song would be faster. I didn't expect that I would win!"

"I just don't understand. I read this book all night and memorized the knot-tying method dozens of times, but why can't I beat Song An! Song An, do you have a trick? Why are you so fast?"

Wang Xiaoguang slapped a"South American Cultural Dictionary" and said angrily.

Fang Yiren raised his glasses and said without thinking,"Praising an adult man for being faster is actually not a good thing."

Wang Xiaoguang and Feng Jing were stunned and looked at Fang Yiren at the same time.

Song An glanced at Fang Yiren. He had come to the technical department several times, and Fang Yiren didn't pay much attention to the occasion every time he spoke.

But in the entire technical department, Fang Yiren still has the highest technical level.

Song An felt that if his analysis was not wrong, Fang Yiren should suffer from Asperger's syndrome.

People with this symptom have great difficulty in socializing and poor language organization skills, but their IQ is extremely high.

Many famous figures in history, such as Einstein, Newton, Leonardo da Vinci, and Rodin, are believed by psychologists to suffer from varying degrees of Asperger's syndrome.

"Xiao Song, don't worry about it. Lao Fang is not very good at talking, but he has no bad intentions.

Wang Xiaoguang said quickly, worried that Song An would be angry.

Song An shook his head and said,"By the way, I came here this time to ask you to help me check the personal information of Sun Zhi, the head of the security department of Xinghui Machinery Factory."

"This is a very simple matter. You even know the other party's work unit, so you should be able to find it in your office."Wang Xiaoguang looked at Song An in confusion.

"I suspect that Section Chief Sun may have a son or nephew named Sun Dapeng, and this Sun Dapeng is very likely the real murderer of the Hetan serial murder case. If this is true,........."

Before Song An finished speaking, Fang Yiren immediately said,"If this is true, Sun Dapeng may have changed his name later, or he has been using a fake identity. Let me check it out!"

"Lao Fang's computer skills are the best in our department. Feng Jing said with a smile

"OK, thank you, Lao Fang, call me anytime!"

Song An said goodbye to the technical department and came to the office of Team 6, calling Tian Rui.

"Teacher Song, it's almost noon, I would like to treat you to barbecue. There is a barbecue restaurant in Lazhu Hutong, I have been there with my classmates before, the taste is very authentic!"

Tian Rui said with a smile, the last time Song An treated her to barbecue, she has been thinking about returning the favor these two days.

Tian Rui's mother used to teach her that girls should not always think about taking advantage of others, but should learn to reciprocate, otherwise they will be looked down upon.

When Song An walks alone, he walks very fast, which is also the instinct of being a criminal policeman.

But when he is with Tian Rui, as long as the task is not particularly urgent, Song An always consciously slows down his pace

""Tian Rui, I just saw you rummaging through your wallet in the office. Are you short of money for this month's living expenses?"

Song An said with a smile.

Tian Rui smiled embarrassedly,"It's okay, Teacher Song, I'm rich! Besides, it's only natural for the apprentice to treat the master to a meal.""

"It is only natural for a master to love his apprentice. Come on, little girl, I'll treat you!"

Song An pulled Tian Rui into the car without saying anything.

Tian Rui sat in the passenger seat, thinking about what Song An had just said. The more she thought about it, the warmer she felt, and she smiled secretly again.

Song An glanced at her and said,"Tian Rui, you won't be paid during the internship period. If you don't have enough living expenses, remember to ask me for it. Don't be polite."

"No need, Mr. Song, that's not appropriate. Tian Rui said embarrassedly.

"There's nothing inappropriate about it. Haven't you heard that an apprentice is half a son to his master, and you are half a daughter to me?" Song An said while driving seriously. Tian Rui got anxious all of a sudden,"Not a daughter, I won't be your daughter, I will never call you dad, Teacher Song is taking advantage of me, humph!"

Song An laughed out loud. He remembered the first time he met Tian Rui. The girl snorted at him three times in one night.

Barbecue is a traditional delicacy of old Jibei. Fruit wood firewood is burned under the charcoal basin, and a round board made of iron bars is placed on the firewood. The strange fragrance of the burning fruit wood drills into people's nostrils.

Put thin slices of mutton or beef on the round board, and then use long chopsticks with delicious seasonings to roast the mutton back and forth on the round board.

The fragrance of fruit wood and meat mixed together, the taste is so delicious that it makes people salivate.

Tian Rui was reluctant to let Song An spend more money, so she only ordered half a catty of mutton, and ordered some cheap ingredients such as fish tofu, meat-stuffed mushrooms, grilled chicken wings, and potato chips.

After a plate of meat was eaten, hot oil was sizzling, and the aroma slowly rose with the white mist, and people's mood became better and better

"Teacher Song, cheers! Thank you for meeting you!"

Tian Rui raised a bottle of Arctic Ocean and clinked it with Song An's soda.

Because it was during work, the two could not drink alcohol and could only drink beverages instead.

Ding~

The two glass bottles collided with each other, making a very pleasant crisp sound.

In the red firelight, Tian Rui's rosy face was reflected. She smiled very happily, her eyes curved into crescents, revealing a row of neat white teeth.

Just after dinner, Fang Yiren's call came in.

"Song An, you are right! The man named Sun Zhi does have a son named Sun Dapeng, who also works at Xinghui Machinery Factory. Sun Dapeng's original name was Sun Xiaoyin, he is 26 years old, and has a junior high school education. Five years ago, he changed his name in his rural hometown, Guokou County.
